I NURSING BOTTLE Filed NOV. 5, 1954 United The present invention relatesto improvements in nurs ing bottles and has reference more particularlyto a bottle that is adapted for a single use and then discarded.

One of the important objects of the present invention is to provide anursing bottle that is of a collapsible nature so that it can bepackaged and shipped very easily.

Another important object is to provide a nursing bottle that includes anouter casing having an inner corrugated liner that will serve as aninsulating medium for the body of the bottle, thereby maintaining thetemperature of the contents of the bottle from changing quickly.

A still further object is to provide a nursing bottle of the abovementioned character wherein the casing is open at its bottom to form anupright support for the bottle while the latter is being filled.

A still further object is to provide a nursing bottle that will beinexpensive and simple in its manufacture and sale.

Qther objects and advantages will become apparent during the course ofthe following description.

In the accompanying drawing forming a part of this specification and inwhich like reference characters designate corresponding parts throughoutthe several views:

Figure 1 is a perspective view of the complete nursing bottle with anipple attached to the mouth of the bottle.

Figure 2 is a perspective view of the cylindrical outer casing forming asalient part of the present invention.

Figure 3 is a perspective view of the flanged sleeve.

Figure 4 is a side elevation of the inner bag unit.

Figure 5 is a transverse section taken on the line 5-5 of Figure 4.

Figure 6 is a vertical sectional view taken on the line 6-6 of Figure 4.

Figure 7 is a transverse section taken on the line 7-7 of Figure 4.

Figure 8 is a fragmentary view showing the flanged sleeve disposedaround the open upper portion of the bag unit.

Figure 9 is a vertical sectional view through the assembled bottle.

Figure 10 is a transverse section taken on the line 10-40 of Figure 9,and

Figure 11 is an edge elevation of the bag unit with the flanged sleeveattached thereto.

In the drawing, the numeral 1 designates generally my improved nursingbottle construction, the same comprising an outer cylindrical casing 2formed of any suitable material, preferably cellophane. This casing isopen at its respective ends as clearly illustrated in the drawing.

A corrugated liner 3 is provided on the interior of the casing as moreclearly shown in Figure 2 and the purpose of this, liner will bepresently described. The vertically corrugated liner may be united tothe inner surface of the cellophane casing 2 by an adhesive. Further,the liner extends for the full height of the casing.

Forming a salient part of the bottle construction is the flexible bagmember 4 formed of any suitable material such as plastic or the like.This bag is open at its top and is normally flat as shown in Figures 5,6 and 7. The open upper end portion of the bag is flared as indicated at5, for a purpose, also to be presently described.

A sleeve 6 is formed with an outwardly extending flange 7 at its top.The flared upper end portion of the bag 4 is disposed through the sleeve6 and the outer extremity 8 of the flared portion 5 is disposed over theflange 7 and downwardly against the outer face of the sleeve 6 andunited thereto in any suitable manner so that the flanged sleeve coactswith the open upper end of the bag to provide a mouth therefor.

In assembling the bottle, the flexible bag and its attached sleeve aredisposed within the outer casing 2 and the upper portion of the casingis restricted and sealed around the outer face of the sleeve 6 and theportion 8 of the bag that surrounds the sleeve. This is clearlyillustratedin Figure 9 of the drawing.

With the parts thus assembled, the bag may be filled with a suitablequantity of powdered milk through its mouth, after which water is added,also by pouring the same into the bag through its mouth. The bottle maybe shaken to thoroughly mix the contents. A nipple 9 may be placed overthe mouth of the bottle as shown in the drawing.

While my improved, disposable, collapsible nursing bottle is intendedprincipally for feedings made from powdered milk or special formulas inpowdered form, it may, of course, be used for feedings of whole milk orother liquid.

When the bag is filled it will of course be extended and touch thecorrugated liner 3. This liner serves to insulate the bag so that thecontents may be kept warm or cold for a longer period, thus keeping thetemperature of the contents of the bottle from quickly changing.

By having the lower end of the casing open and extending slightly belowthe bottom of the bag, the casing will serve as an upright support forthe bottle while the bag is being filled.

After the bottle has been used once in feeding a child, the same may bediscarded.

It will thus be seen from the foregoing description that I have provideda single use nursing bottle and due to its simplicity the same can bemanufactured and assembled at a very low cost. Further, the bottlestructure is collapsible for easy packaging and shipping.

While I have shown the preferred embodiment of my invention, it is to beunderstood that various changes in the size, shape and arrangement ofparts may be resorted to without departing from the spirit of theinvention and the scope of the appended claim.

Having thus described my invention, what I claim is:

A nursing bottle adapted for a single use, comprising a flexible andexpansible inner bag having a cylindrical body portion, a restrictedneck portion and an outwardly flared extremity, a cylindrical sleevehaving a radially outwardly projecting flange at one end thereof, saidrestricted bag neck portion extending through said sleeve from the endthereof opposite said flange and secured to the inner wall thereof, andsaid outwardly flared extrernity being folded outwardly over said sleeveand being in engagement with the outer end thereof, the peripheralsurface of said flange, the lower edge of said flange and the outercylindrical surface of the sleeve and being secured thereto, and an openended outer cellophane casing surrounding said inner bag and beingprovided with a corrugated liner adhesively secured thereto, said casinghaving a restricted neck portion surrounding the portion of said bagengaged with the outer cylindrical surface of said sleeve and beingsecured thereto.
